Excellent! This works. Thank you.

one little issue left is that QTKit does not seem to work when trying  
to use it from PPC CCL 1.2:

Warning: Interface file #P"/Applications/Clozure CL 1.2/Clozure CL.app/ 
Contents/Resources/darwin-headers/qtkit/objc-classes.cdb" does not  
exist, and the containing directory does not exist.

I checked my version of PPC CCL (1.2-r9226-RC1  (DarwinPPC32)!) does  
not have the qtkit headers.

is this a limitation of QTKit or PPC CCL?
